Dynmap fullrender only rendering overworld after upgrade to 1.21.11

[BySwiizen]

Issue Description: Since upgrading to 1.21.11 and updating plugins, I’m having an issue with Dynmap. When I try to render the Nether or End using /dynmap fullrender world_nether or /dynmap fullrender world_the_end, Dynmap only renders the overworld and never renders the other worlds. However, if I generate a new Nether or End world, the render works correctly.

• Dynmap Version: dynmap-3.8
• Server Version: spigot 1.21.11 build 4594
• Pastebin of Configuration.txt: https://pastebin.com/HSGrjMxg
• Server Host (if applicable): Selfhosted
• Steps to Replicate: Put your server in the latest version and update Dynmap. Fullrender the nether and the end.
